With the aim to propose alternative solutions for Multi Mirror Telescopes, we present some ideas about a MMT for High Resolution Spectroscopy purposes. The alternative solution is intended both in technical conception and in economical costs.

This possible project consider the use of a system of 36 mirrors about 1.5 meter in diameter, collecting light independently each other and transmitting the light down to the slit spectrograph by optical fibers.

To reduce mirror costs and structural weight, we propose to develop the “replique” technique over light-weighted supports modelled and adjusted over a master convex mirror.

Different project design for a modular hive structure are considered.
